Bombardier Global 5500 vs Bombardier Global 6500 vs Dassault Falcon 6x vs Gulfstream G500 vs Gulfstream G650er

In category, the Bombardier Global 5500 and Gulfstream G500 sit in the large-cabin, long-range class, while the Bombardier Global 6500 and Dassault Falcon 6X are large-cabin aircraft that lean further into ultra-long-range comfort and space. The Gulfstream G650ER is the flagship ultra-long-range heavy jet in this group. On range, the Global 5500 and G500 are broadly comparable long-range performers, typically in the mid‑5,000 to about 6,000 nautical mile bracket depending on mission assumptions. The Falcon 6X and Global 6500 generally step up into the mid‑6,000 nautical mile class, enabling more true intercontinental city pairs. The G650ER is the clear range leader, commonly cited around the mid‑7,000 nautical mile class, offering the widest nonstop network potential. For passenger capacity, all can be configured for roughly 8 to 19 passengers depending on layout, but typical executive arrangements cluster around 10 to 16. The Global 6500, Falcon 6X, and G650ER tend to offer the most flexible multi-zone cabin configurations, with the Global 5500 and G500 slightly smaller but still fully large-cabin in feel.
